• One of important reasons behind destruction of species diversity is habitat loss and fragmentation by cutting trees. 
• This is most important cause of driving animals and plants to extinction. The most dramatic examples of habitat loss come from tropical rainforests.
• Once covering more than 14 percent of Earth's land surface, se rainforests now cover no more than 6 percent. 
• They are being destroyed fast.

Greenhouse gases such as carbon dioxide, methane, nitrous oxide, water vapours trap heat radiating from earth towards space making earth warmer. The increased amount of se gases block Heat from escaping and y present in earth's atmosphere for more than ir expected period. Scientist attributes cause of global warming to such semi-permanently existing gases 'forcing' climate change.

Forest destruction i.e. deforestation has many after effects, it leads to soil erosion, loss of habitat, etiction of wildlife, floods & drought conditions.

• On basis of origin, re are different types of air pollutants. 
• The primary pollutant is directly released into atmosphere from wastes. The secondary pollutants are produced due to reaction of primary pollutant with some or gases. 
• The ozone is considered as secondary air pollutant because it is formed due to interaction of volatile organic compounds in atmosphere. 
• Thus, correct answer is option C.
